The attainment of these and further objects will be apparent from the accompanying specification taken in conjunction with the drawings forming a part thereof.

In'the drawings, Figure 1 shows a blank piece of pasteboard from which the carton is made. Figure 2 is a view of the two sections partially assembled. Figure 3 is a view of thecomplete carton closed. Figure 4 is an enlarged fragmentary view showing the manner in which the top of the carton is held closed. Figure 5 is an enlarged fragmentary view showing the manner in which the carton is colla sed. Figures 6, 7, and 8 illustrate a mo ifiecl form of construction and correspond respectively to Figures 1, 2, and 3. Referring now to igure 1, the eneral 3o shape of the blank piece of paper, car board,

pasteboard or the like, from which the carton is made, is shown. The dotted lines indicate the lines along which the blank is creased for folding while the full lines lndicate the lines along which the blank is cut. The strips into which the paper is divided have been numbered 1 to 7. The blank is divided into two sections a and b, the two sections being integral at the strip 5-5 and cut apart between the strips 1, 2. 3, 4, 6 and 7 and the corresponding strips 1. 2, 4', 6 and 7 The blank piece of paper 1s folded along the dotted lines and the strip 7 1s pasted to the strip 3. When the strip is pasted to the longitudinal strip 3, the strip 61s in a horizontal plane parallelto the plane of the bottom 4. The strip 5' is folded along-the dotted line 21 until the strips 5 and 5' are opposite one another and the two opposlte edges o of the strips are pasted or glued together at the very end, thus securely holding the two sections together.

The strip 6 is divided into a number of flaps 8 to 14 inclusive. The transverse walls that dividethe interior ofthe carton into a number of cells are formed by foldin the flaps down at right angles to the plane 0 the paper along the dotted lines 15. The flap 14 is folded along the line 16, and the flap 8 along the line 17 The flaps 8, 11, 12,- and 14 each have a projection 19 which engages With the corresponding slits 20 when the flaps are folded down, thus serving to hold them in place and give the carton rigidity. The end wall 5 has two upward projecting tabs 26 one 5, at each of the points where the locks 25 are to be passed under triangular corners about which the flaps 9 and 12 fold. The object'of .these tabs is to facilitate the closing of the carton, the tab 26 acting as a guide for the lock 25, as may be seen in Figure 4. The height of the flaps 10 to 14, slightly exceeds the height of the wall 5, with the result that when the flaps are folded down in position, the lower end of the flap is forced to give way and slightly bend, as may be seen at 30in Figure 4. Thus the flaps when folded, are additionally held in place by the frictional engagement of the bent portion 30 with the bottom of the carton.

The complete carton seen in Figure 3 may be severed into its two component cartons a and b by inserting a knife between the longitudinal walls 5 and 5 and cutting those walls apart at the line 21, and also at the opposite end of the walls where they are pasted together.

The assembled carton with the Walls 6 and 6 in the horizontal position may be collapsed for shipment by opening the top 2 and 2 until the tops are in a plane with the corresponding longitudinal walls 3 and 3, and bringing those two planestogether by folding the walls 46 and 46' down, the walls 55 being joined. This is partially shown in Figure 5. It is of course understood that the carton is further collapsed from the position shown in Figure 5 until the walls 2 and '2 come together, with the wall 6 resting 1 against the wall 3 and the wall 6 against the wall 3'. a A

Referrin now to Figures 6,7, and 8 showing a modi ed form of construction, the blank from which the carton is made is divided into a number of sections 41 to 47 and 41 to 47" which correspoiid respectively and are identical to the strips 1 to 7 and 1' to ,7 of the carton previously described. The assembly of the carton to the stage shown in Figure 7 is identical to that shown in Figure 2. To complete the assembly of the carton, the sections 0; and b are folded until the longitudinal walls 45 and 45 are back to back, the wall 50 constituting one of the transverse walls to hold the two sections together. The edge 52 of the flap 51 which is integral with the section 43 is then pasted to the wall-43 to hold the other end of the two cartons together.

The transverse walls 50 and 51 are not joined to the walls 4545- hence the carton shown in Figure 8 may be collapsed in the same manner as is the carton shown in Figure 3. Upon collapsing the carton, as the walls 43 and 4.3

are brought together, the transverse walls and 51 fold outward at their respective-centers.- e

To sever the carton shown in Figure 8 into its two component parts it is: only necessary to cut the transverse walls 50 and 51, since those walls constitute the sole means for holding the two sections together.

While in Figures 2 and 7 the flapsS to 14 are shown folded down, it is of course understood that this is for illustrative purposes only. In the process of assembly of the car- I tons those flaps are not folded down until the walls 5 and 5 have been secured together or until the portion 52 has been pasted to the longitudinal strip 43. The carton is completed, folded and shipped, without the flaps 8 to 14 having been folded down. Those flaps are folded down when the eggs are to be put into the carton.

In compliance with the requirements of the patent statutes I'haveherein described certain preferred embodiments of my invention. It is however to be understood that the same are shown for illustrative purposes only and I do not wish to be limited to the precise construction shown.
